In laboratory tests, left- and right-handers associate positive ideas like honesty and intelligence with their dominant side of space and negative ideas with their non-dominant side. To find out whether people link 'good' with 'dominant' beyond the laboratory, Casasanto and co-author Kyle Jasmin examined spontaneous gestures during positive and negative speech in the final debates of the most recent US presidential elections.
The 2004 and 2008 elections involved two right-handers (Kerry, Bush) and two left-handers (Obama, McCain). Casasanto and Jasmin found that right-handed candidates made a greater proportion of right-hand gestures when expressing positive ideas and left-hand gestures when expressing negative thoughts. But the opposite was found for the left-handers, who favored their left hand more for the positive and their right hand for the negative. |

Across many cultures, expressions in language link 'good' with right (the right answer) and 'bad' with left (two left feet). Likewise, classical treatises instruct politicians to gesture mostly with their right hand, and only to use their left hand when delivering bad news.
'Right' and 'left' are also linked with political views, but the candidates' spontaneous gestures did not follow party lines. Both right-handers showed the 'good is right' pattern, and both left-handers the 'good is left' pattern. The association of good things with one's dominant side is something Democrats and Republicans appear to agree on.
So, the hand people use to make most of their gestures with may be a clue to whether they think what they are saying is good or bad, as long as you know their dominant hand. As us lefties are in a minority, is it possible that because we mainly use our left hand for gestures about good things, the righties may actually get the impression that we think it is actually bad?
This is getting too complicated but it is an interesting thought! If you want to know more, this is a link to the original research paper.

I do however do one thing right handed which is eating food. I would argue that in fact holding the fork in your left hand is in fact left handed on the basis that the eye/hand co-ordination required to get the food from the plate to your mouth is best undertaken by using your dominant hand. I therefore consider that all right handers are using the utensils the wrong way round.
With regards to handshaking we need to look back to a time when a handshake rendered a right hander defenceless as they would be using their sword hand. This reinforced the belief that leftys were "sinister" (a heraldic term) and untrustworthy. In fact, in the days of the Borges in Italy they would hire left handed assassins to carry out vendettas.
I have two nephews out of three that happen to be left-handed due to my father being left-handed. i meet a lot of left handed people and think that it is terrible that people used to try to "change" children's handedness because of some stupid misguided superstitions. I am mostly right handed but use my left hand more now because of my job and my nephews and find that it has increased my memory and helped my brain a little. It is supposed to help your brain by using your non-dominant hand every so often for tasks like brushing your teeth or scrubbing the floor. It puts me more in my right brain, like you. Be proud of being a lefty, just like the president.
I use my left hand for everything except eating.
Now the interesting thing is i eat from my right hand finger but i use my left hand to pick the spoon or pick the boul.
Also i shake hand with right hand.
I am lefty, Its heridity of my father.
But i lm proud to be lefty.
shakes hands with mt right, opens doors with my right, kicks a ball with my left foot and swims with my right side being stronger. Am
i strange or just me?
My grnadaughter is a leftie as are three of my cousins, my neices are also lefties, all female, what a wonderous world we live in!!
By the way my spacial awareness is top notch, need to fit in furniture, ask for me!
I understand the term is cross dominance.
Yet all my life I have thought of myself as a lefty and I am proud to be one.
At my first school at age 5 my mother asked the teacher about my using the left hand and was assured by her (a lady approaching retirement then 1943) that children were no longer made to use the right. One year later we moved and I changed school. My new teacher was a young lady straight out of training and she punished me and the other lefties. I used to hear her approach and change the pen over to the right and change it back when she had passed by.
Writing lessons were a nightmare for us having to use pens with nibs and an inkwell. Our hands smeared the ink so teacher knew we'd been using the left hand. Each year we waited to see if our new teacher tolerated lefties.
I never told my parents because in those days you took the rows you got at school without question.
I will from now on pay attention to my own and others' gestures. Up till now I hadn't thought about it. This is an interesting point indeed.
I wish things had been that easy in the regular school I attended as a child (I'm not deaf, by the way). There was some limited attempt to switch the lefties, but we prevailed, and I do everything left-handed (you should see my inventive way of using a right-handed can opener). I think the most difficult part of my education was taking notes at university, since they had those flip-up desks that were on the right side of the chairs... but I usually managed to get two chairs, so I could use the desk from the one on my left.
Oh, and I fence, and once won a bout at the national level (beating the top fencer in the group I was in) because my opponent didn't notice that I was left-handed.
I'm left-handed. I'm not sure whether since I was born or because of and accident i had since i was 5. I was the only lefty in my family but i'm not sure about my grandparents.
when i was small, i felt weird from the others but when i grow up and meet friends like me (i mean lefties) i felt we were unique.
I always confuse. when right-handed say right, i respond to left :)
(so i think i'm naturally left)
My friends always said that lefties are creative, they can draw nicely.. yes, i can but not so nice... :)
My First Grade teacher slapped my face, made me sit on a chair, face the blackboard in front of the room. I can still see that little chair and the blackboard in my mind. Her hand left her a print on my face and when my father found out about her doing that, he went to the school and protested. I was too young and scared to really know what that outcome was.
It scared me so much I suppose, that I became a right hander, except for the fact the teacher wasn't at our kitchen table to witness me eating with my left hand and that is mainly the only thing I do with my left hand, although I do find myself doing odds and ends with my left hand.
I guess I am a little stubborn, as today I practice writing with my left hand and have not forgiven that First Grade teacher for what she had done, I have resented her practice of changing little children to be right handed instead of left handed. I was going to school in the "Spring Street Elementary School" in Piqua, Ohio at the time. No need to mention her name, as I am fairly sure she has passed away by this time.
My sister and my son are both left handed but not my parents.
I am a lefty, use the mouse with the left hand, write with the left hand, (which has its problems at work and I need to write at the same time!) have my knife and fork the 'wrong way round' etc but at 7 years old was forced to learn to write with the right hand as I broke my arm and had it in plaster for 12 weeks.
I stood up and asked..."But, What if you're left-handed"? Everyone in the roon laughed, but, I never got a straight answer!!!!
My point is, if you're a lefty, YOU ARE A LEFTY...and I'm so very proud to be one!!!
Which hand would be called positive or negative?
